Title: Flame detector for burner
Inventor: MORIMOTO OSAMU
IPC: F23N5/14
Filed: 1978-10-13
Abstract: PURPOSE: To positively detect the flames at a burner, by detecting the change of the electric resistance of a flame-resisting wire by means of a detecting circuit.  
     CONSTITUTION: When a burner 1 is not ignited, a bridge circuit 8 keeps equilibrium because there is no flame, and output is not emitted to output terminals 13. When the burner 1 is ignited, the temperature of a fire-proof resistance wire 6 rises by heat energy radiated from flames 5, and the electric resistance is enlarged in response to the rise. Thus, the equilibrium of the bridge circuit 8 is broken and fixed output voltage appears between the output terminals 13. Flame detecting signals can be obtained by amplifying and extracting the output voltage by means of a proper amplifier. Consequently, flames can positively be detected even if the flames are beforehand formed without regard to the change of a combustion condition, the change-over of fuel, etc.
